Water, Boiler Water and Steam Quality for Power Plants / Industrial Plants. This new guideline replaces the former "VGB Guideline for Boiler Feed Water, Boiler Water and of Steam Generators with a Permissible Operating Pressure > 68 bar, October 1988 Edition".
Mar 02, 2020 · Since water tube boilers have more surface area than fire tube boilers, they tend to be a bit more prone to scaling. This isn't an issue with Miura boilers, however, because we equip our boilers with meticulous monitoring systems and control devices that ensure minor water quality issues are detected and addressed long before they can impact the performance or efficiency of your boiler.

water quality control criteria. In February 1961, these were stipulated by JIS B 8223 (titled "Water conditioning for boiler feed water and boiler water"). JIS B 8223, which stipulates the required water quality for boilers and turbines of thermal power plants, is regularly amended based on
The boiler water should be maintained at pH 11. This may require an addition of alkaline if the water is not soft. A chemical called a sludge conditioner can be added to treat the solids so that they drop out (precipitate). These treated solids then must be removed from the boiler by blowoff.
• ST - water up to 700°C and pressure up to 30 MPa circulating in 3 sections: steam economizer, evaporator and superheater Circulating water quality: • High water quality kept by continuous blowdown and degassing • Return condensate – treatment (filtration, deionization by H+catex, degassing)
